This fixes <rdar://problem/8869639>. I also filed PR9184 on doing this sort of
thing automatically, but it seems easier to just change the ordering of the
passes if this is the only case.

This is a hack because we really should only search in the 'include/clang/StaticAnalyzer' directory
if we are in 'lib/StaticAnalyzer'.  My CMake knowledge is limited, so I appeal to anyone with
more expertise.

llvm-svn: 125252

Split 'include/clang/StaticAnalyzer' into 'include/clang/StaticAnalyzer/Core' and 'include/clang/StaticAnalyzer/Checkers'.

This layout matches lib/StaticAnalyzer, which corresponds to two StaticAnalyzer libraries.

When matching operands for a candidate opcode match in the auto-generated
AsmMatcher, check each operand against the expected operand match class.
Previously, operands were classified independently of the opcode being
handled, which led to difficulties when operand match classes were
more complicated than simple subclass relationships.

to update this variable instead of the original m_inst_cpsr, which should be
the cached copy of the CPSR at the beginning of executing the opcode.

Loop splitting is better handled by the more generic global region splitting
